Question

克隆回购后，npm install＆amp;＆amp; ionic cordova build android --prod向我显示以下错误。

TypeError：无法读取属性＆＃39;标记＆＃39;未定义的 at checkUnreachable（F：\ Works \ Projects \ ionic-bokfinder \ node_modules \ typescript \ lib \ typescript.js：24905：31）在bindChildrenWorker（F：\ Works \ Projects \ ionic-bokfinder \ node_modules \ typescript \ lib \ typescript.js：23111：17）在bindChildren（F：\ Works \ Projects \ ionic-bokfinder \ node_modules \ typescript \ lib \ typescript.js：23055：17） at bind（F：\ Works \ Projects \ ionic-bokfinder \ node_modules \ typescript \ lib \ typescript.js：24319：21）在bindSourceFile

我确信之前没有遇到任何问题。这是我的系统信息和package.json。

系统：

    Node : v8.10.0
    npm  : 5.6.0
    OS   : Windows 10

的package.json：

"dependencies": {
    "@angular/common": "5.0.3",
    "@angular/compiler": "5.0.3",
    "@angular/compiler-cli": "5.0.3",

    "ts-node": "4.1.0",
    "tslint": "5.9.1",
    "typescript": "2.4.2"
  },

我猜这个问题与@ionic/app-scripts issue有关。

Answer 1

删除@angular/cli应该适合您

如果没有，请将Typescript版本更改为~2.6.2。

@angular/cli 1.7.3仅适用于Typescript ~2.6.2。

Answer 2

我正在使用角度5和离子v3。对我来说，这些变化是：

"@types/node": "^9.6.55",
"typescript": "3.7.4",
"@ionic/app-scripts": "3.2.3",

如果您使用的是@angular/cli或@angular-devkit，在我的情况下，为了正确地使用--prod标签，我必须将其删除。

请确保还删除了node_modules并先执行npm cache clean -f，然后再执行npm i（也许还可以删除package-lock.json）
